Sometimes Crafty gives me a headache. I was sitting there, minding my own business, when all of a sudden pow! and Crafty wins another one. Must be something to this smp business. Anyway, on ICC Crafty runs on a 2x 2.8ghz xeon. It found Rxg6 in about a minute, if you count my thinking time plus its thinking time (assuming it pondered correctly, which it probably did). If I run the same position on my p4 2.8ghz, it takes Crafty 4:44 to find the move. I suppose the hash could affect things, but that's still quite a speedup. Here's the position. Finding Rxg6 probably depends in large part on king-safety, since Amateur likes it fairly quickly (p4 2.8ghz): [d]2rq1r1k/1pp1bp2/p5pp/1n1Pp3/2B1N3/4PP2/PPQ2PRP/6RK w - - 10 -28 283 1103649 Qb3 Nd6 Bd3 Nxe4 11 -23 452 1839082 Qb3 Nd6 Bd3 Nxe4 fxe4 Rb8 f4 Bc5 Bc2 Qd6 f5 Rg8 fxg6 fxg6 12 -14 889 3652804 Qb3 Nd6 Bd3 Bh4 13 -9 1572 6584263 Qb3 Nd6 Bd3 Nxe4 fxe4 Rb8 Qc3 Qd6 Rc1 Rc8 f4 Bf6 Qc5 Qd7 14 -5 4219 17715012 Qb3 Nd6 Bd3 Ra8 Nxd6 Qxd6 Qc3 Rd8 e4 14 6 6427 26545535 Rxg6 fxg6 Rxg6 Rf5
